Lesson details
Key learning points
- If one factor is made one hundred times the size, the product will be one hundred times the size.
- One factor has been multiplied by 100 so the product is multiplied by 100
- When multiplying two numbers, if either factor is made 100 times the size, the product will be 100 times the size.
- 6 multiplied by 300 is equal to 600 multiplied by 3 or 6 hundreds multiplied by 3
Keywords
Factor - A factor is a number which exactly divides another whole number.
Product - A product is the result of two or more numbers multiplied together.
Common misconception
Place value counters don't have proportionality in the same way that Base 10 does which can make the concepts here more abstract.
Smaller multiplications can be used with Base 10 to model scaling to start off with. Try 2 × 1 or 3 × 1 scaling up to become 2 × 100 or 3 × 100 with Base 10 and then put this modelling side-by-side with place value counters to make the links.
